Specification of Letters Patent.-

Patented sept. ze, .1908.

Application med umm, 190s. serial. No. 419,679.

,which the following is-a full, clear, and exact description. Y

The invention relates to automatic player pianos, and its object is to provide new and v lmproved folding bellows pedals, arranged to showing the bellows same, showing the permit the user of the piano to conveniently and quickly-move the bellows pedals into an extended active position or'into a folded inactive' osition, to allow the player to make use of t el action pedals when playing the piano by hand.

'The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming apart of this specification, in which similar 'characters of reference indicate corres onding parts in all the views.

igure 1 1s a transverse section of a player piano provided with the improvement and pedals in an extended or active position; Fi 2 is a like viewof the bellows edals in a folded position, and Fig. 3 is a ront view 'of the same, the fixed front and door being removed arid the key board being in section.

The casing A of the player piano supports the key board base B, below which is arraliged'a fixed front C, on the lower edge of which is mounted to swing a door D, in the having their movable members F wlth forwardly-extending'arms F2 tending rod rear of which and of the said 'fixed front C is located the suction chamber E from which the .air is exhausted by suction bellows F provided pivotally connected by links G with the pedals H, adapted to extend in the door opening of the door D when the latter is swung into an open position, as shown in Fig. 1, or to be folded 1n the rear. of the said door D at the time the door is closed, as indicated in Fig. 2. The pedals H are g'voted on a longitudinally-exforming art of a frame J fulcrumed atJ on brac ets K attached to the casing Av at end of the frame J being adapted to rest o'n pedals H are extended,

crank lever N, fulcrurned at N on a bracket K held on the bottom of the casing A, and the said bell crank lever N is pivotally 4connected by a link O with the arm. P of a three-armed lever P, fulcrumed at P2 on the suction chamber E, as illustrated in the drawings. The arm P3 of the three-armed lever P is pivotally connected by a link Q with a slide R, mounted to slide transversely in bearings B formed o n the under side of the key board base B, preferably at the lefthandA side thereof, as plainly indicated in Fig. 3. The slide R is rovided near its forward end/wivh a knob 1', to pei-mit the user of the playe piano to impart a slidin inotion transverse of the keyboard to the slide R.

The third arm P of the three-armed lever P is pivotally connected by a .link S with a lever T fulcrumed at T on the back of the fixed front C, and the said lever T is pivotally connected by a link U with the arm V of a bell cr'ank lever V fulcrumed at V2 on the back of the fixed front C, adjacent to the uper or hinged end of the door D. The arm V3 of the lever V is curved and is rovided at its free end with a friction roller engaging the rear face of the door D, and the said arm V3I is connected by a spring W with the said door D to hold the latter in contact with the friction roller V4. A spring X attached t0 the under side of the key board base B connects with the arm P4 'of the three-armed lever P, so 'as to counterbalance the 'pedals H and the operating mechanism connected therewith.

Now when the several parts are in thc position illustrated in Fig. 2, the pedals H and the entireoperating mechanism for the same are folded in the s ace in the rear of the front C and the closed dbor D, to be invisible from the outside of the casing. Now when it is desired to make use of the pedals for actuating the pla er iano mechanically, the operator takes ol of the knob R and draws the slideR forward, so that a swinging motion is given by the link Q to the three-armed lever P, whereby the door D is swung forwardly and u wardly into an open position, as shown in Fig. 1, and at the same time the pedal frame J is swungforward and down-y ally controlled actiiating member.
